HCOR: a high-throughput coding-aware opportunistic routing for inter-flow network coding in wireless mesh networks

Coding-aware routing is an effective approach to create more coding opportunities in inter-flow network coding. To the best of our knowledge, most of the coding-aware routing schemes focus on maximizing the coding opportunities. However, for opportunistic transmission, the throughput is not always increased with the increase of coding opportunities. In this paper, we explore why...

Extraventricular neurocytoma of the sellar region: case report and literature review

Introduction The extraventricular neurocytoma of the sellar region (EVNSR) is a rare disease, it is difficult to make exact diagnosis of and operate on patients. Retrospectively analysed the clinical manifestations, image features, therapy methods and outcomes among patients with EVNSR, to investigate the epidemiological characteristics, image features, diagnosis, treatment and...

C1 regularity of the stable subspaces with a general nonuniform dichotomy

For nonautonomous linear difference equations, we establish C1 regularity of the stable subspaces under sufficiently C1-parameterized perturbations. We consider the general case of nonuniform dichotomies, which corresponds to the existence of what we call nonuniform (μ, ν)-dichotomies. Mathematics Subject Classification 2000: Primary 34D09; 34D10; 37D99.

General split equality problems in Hilbert spaces

A new convex feasibility problem, the split equality problem (SEP), has been proposed by Moudafi and Byrne. The SEP was solved through the ACQA and ARCQA algorithms. In this paper the SEPs are extended to infinite-dimensional SEPs in Hilbert spaces and we established the strong convergence of a proposed algorithm to a solution of general split equality problems (GSEPs).

Characteristics of CpG Islands and their quasispecies of full-length hepatitis B virus genomes from patients at different phases of infection

Background CpG islands in hepatitis B virus (HBV) genome are potential targets for methylation mediated gene silencing, and may be involved in the pathogenesis of HBV infection. To date, their characteristics in HBV quasispecies (QS) remain largely unknown. The purpose of this study was to investigate the characteristics of CpG islands in HBV QS. Methods Forty patients diagnosed...

Synthesis, crystal structures, and photoluminescence of two silver(I) coordination polymers based on 2-sulfoterephthalic acid and N-donor ligands

The reactions of 2-sulfoterephthalic acid (H3stp) with silver nitrate in the presence of 2-aminopyrimidine (apym) or 2-amino-4,6-dimethylpyrimidine (dapym) generated two 2-D coordination polymers {[Ag3(stp)(apym)3]·2H2O} n (1) and {[Ag2(Hstp)(dapym)2 (H2O)]·H2O} n (2). The complexes have been characterized by single-crystal X-ray diffraction, physico-chemical, and spectroscopic...

Differential radio map-based robust indoor localization

While wireless local area network-based indoor localization is attractive, the problems concerning how to capture the signal-propagating character in the complex dynamic environment and how to accommodate the receiver gain difference of different mobile devices are challenging. In this article, we solve these problems by modeling them as common mode noise and develop a...
